Simple Network

The simple network models hop-by-hop network traversal, but abstracts out detailed modeling within the switches. The switches are modeled in simple/ while the links are modeled in simple/ The flow-control is implemented by monitoring the available buffers and available bandwidth in output links before sending.

  • Configuration:

Simple network uses the generic network parameters in Additional parameters are specified in simple/

    • buffer_size: Size of buffers at each switch input and output ports. A value of 0 implies infinite buffering.
    • endpoint_bandwidth: Bandwidth at the end points of the network in 1000th of byte.
    • adaptive_routing: This enables adaptive routing based on occupancy of output buffers.
